Title: Centrifugal acceleration tester for semiconductor package
Inventor: FUKUI MASAHIRO
IPC: G01M3/00
Filed: 1983-10-21
Abstract: PURPOSE:To test the airtightness of the junction part between the base body and lid body of an insulating container accurately by forming a cut part at the part of a support corresponding to the dead space of an insulating container, and allowing the insulating container to abut on the support only at the outer circumferential end part corresponding to the junction part. CONSTITUTION:When the cut part 23 is formed, the support abuts on the insulating container 3 only at the outer circumferential edge part except the part corresponding to the dead space A of the insulating container 3. When a rotor 11 is rotated at a high speed, the reaction force to centrifugal force is applied to only the outer circumferential end part corresponding to the junction part between the base body 1 and lid body 2 of the container 3 because the insulating container abuts on the support only at the outer circumferential end part, so the lid body of the container is not curved large toward the dead space A of the container and cracking, etc., due to curvature is eliminated completely.

Title: Color cathode-ray tube
Inventor: SHIMADA KOJI
IPC: H01J29/18
Filed: 1992-07-24
Abstract: PURPOSE:To improve color purity characteristics and brightness by increasing the lengthwise arrangement pitch of phosphor dots for the formation of a phosphor screen in a direction from a center section to a peripheral section, according to a specific change rate, and then enlarging the change rate near the peripheral section. CONSTITUTION:The lengthwise direction of a phosphor screen having a phosphor dot array is taken as an X-axis, and the direction orthogonal therewith taken as a Y-axis, with the center of the screen taken as an origin. Then, the pitch of phosphor dot trio array along the X-axis is gradually enlarged along a direction from the origin to the peripheral end of the screen, at the rate of a change within 10%. Furthermore, the rate of a change is gradually increased from an intermediate position between the origin and the peripheral end, for example, the neighborhood of a coordinate point of 150. As a result, curvature can be enlarged, regarding a phase panel and shadow mask sections in a zone from the intermediate position to the peripheral end. Also, the doming of the shadow mask and the improper landing of an electron beam can be lessened, thereby improving color purity characteristics and brightness over the whole area of the screen.

Title: Cathode-ray tube for projection
Inventor: NAITOU YOSHIICHI
IPC: H04N5/74
Filed: 1981-12-11
Abstract: PURPOSE:To offset the generating change of horizontal linearity and fully correct or reduce the misoconvergence caused by the change of horizontal linearity by slanting a projecting optical axis in relation to a screen on a projection screen face. CONSTITUTION:In a CRT1R for projection, the right and left lengths between the central axis 10 of the CRT for projection and the wall surface is assymetrical in the cross section vertical to the central axis 10 of the CRT1R for projection in a funnel and a neck, that is, the left length is shorter than the right length. Therefore, when a deflection yoke is mounted, both the central axis 10 of the CRT for projection and the central axis 14 of the deflection yoke can be made eccentric, and the central axis 10 of the CRT for projection can be set to the left of the central axis 14 of the deflection yoke. On the other hand, a horizontally deflected magnetic field is made more infeuse in its periphery in relation to the central axis 14 of the deflection yoke. As a result, the force 15a of the horizontal deflection of an electron beam, when the beam is deflected left is larger than 15b when it is deflected right.

Abstract: PURPOSE:To retrieve and display automatically the broadcast station-frequency correspondence data classified by district recorded on a tape, by reading out the data just by designating the district by utilizing the music selecting function with program searching of the tape. CONSTITUTION:A cassette tape on which a correspondence table between broadcast stations and frequencies is recorded, is reproduced by a cassette tape recorder 8, and this data is read by a microcomputer 6 with display of the name of the broadcast station which is under reception.

In a retrieving mode the data on only a prefecture where a receiver exists and neighboring prefectures decided in terms of the field intensity are read out. In the correspondence table, an index number is allotted to each prefecture name. Thus the index number is first read into a memory of a microcomputer 6. Then the name of the prefecture containing a receiver is fed into the computer 6 via the index number. Thus it is possible to refer to the index numbers of the neighboring prefectures to be checked.
